RUNNING-GEAR FOR WAGO'NS.

SPECIFICATION forming part of Letters Patent No. 707,520, dated August 19, 1902.

Application filed December 31, 1900. Serial No. 41,748. (No model.)

To [tZZ whom it may concern.-

Be it known that I, FRANK HENRY PIOKARD, a citizen of the United States of America, residing at Hill City, in the county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Running- Gears of Wagons, Buggies, and other Vehicles, of which the following is a specification, reference being had therein to the accompa- IO nying drawings.

My invention relates to certain new and useful improvements in running gears of wagons, buggies, and other vehicles, and has for its object a device of this character,where I 5 in the rear wheels of the vehicle will follow the direction assumed by the front wheels in turning the vehicle, the rear wheels to these ends having their every movement controlled by the front ones.

The invention has for its further object a device of this character which will be ex tremely simple both in its operation and economical construction.

With the above and other objects in view the invention further resides in the novel details of construction and combination of parts to be fully described in the following specification and then set forth in the claims.

Referring to the accompanying drawings,

illustrating the invention, and wherein like characters of reference indicate similar parts throughout the several views, Figure 1 is a top plan View. Fig. 2 is a rear elevation with the wheels removed. Fig. 3 is an elevation of one of the spindles employed for the rear wheels. Fig. 4 is a perspective View of one end of the rear axle. Fig. 5 is an elevation of the forks carried by the telescopic rods. Fig. 6 is a perspective view of one of the arms 4 employed in connection with the rear spindles.

The frame of the vehicle is not unlike those commonlyemployed,thoughIhave illustrated one which may be adjusted through the means of the rear hounds 1 and the coupling or reach 2. The rear axle carries a pair of plates 3 3, which may be secured thereto in any suitable manner, the ends of the plates extending beyond the ends of the axle and being apertured, as at 4 at. The rear wheels are plates 3 3.

mounted on spindles 5,carrying vertical members which are enlarged, as at 6, and which enlarged portion is received between the This vertical member above and below its enlarged portion carries rounded shanks 7, which are received within the apertures 4 4 of the plates 3 3 and are adapted to freely rotate therein. It will be noted that the enlarged portion is flattened on its upper and lower face, as shown at 8 8, which forms a convenient support'for the spindle by reason of its large bearing-surfaces engaging the plates. The rounded shanks 7 are preferably of a length equal to the thickness of the plates and above and below the latter merge into squared shanks 9 9. The front and rear axles are connected by means of horizontal telescopic rods 10 11, moving in planes parallel with one another, the former having a pivotal connection with the front axle, as at 12, and the latter carrying a forked end 13. These telescopic rods permit of the longitudinal adjustment of the vehicle-frame, they being secured in their adjusted position by any means, such as the screws 14. Secured to these square 7 5 shanks 9 9 above and below plates 3 are levers 15, having a square aperture 16 in their one end receiving shanks 9 and forming a pivotal connection with the forks 13 of rods 11 at their other end which will readily commu- 8o nicate any movement of the front Wheels to the rear ones, as will be understood. I may provide Washers 17, which are interposed be tween the levers and the upper faces of the plates, as shown.

It will be perceived that the connectingrods move in planes parallel with one another, which effectually prevents any interference of these rods with each other and causes a positive action in their every movement.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a device of the type set forth, the combination with the front and rear axles of a vehicle, of a pair of plates secured to the rear axles and extending beyond the ends thereof, a spindle carrying a vertical member comprising an enlarged portion received between said plates and rounded shanks extending through the plates, with squared I axle, levers connected to the ends of the vershanks on the ends of the rounded shanks, tical member, and rods movable in parallel levers connected to the squared shanks above relation with each other pivoted to the front and below the axle, and rods carrying a forked axle and carrying forked rear ends pivotally end movably secured to said levers, the other connected to said levers. end of the rods being pivoted to the front In testimony whereof I have signed my axle, said rods being movable in parallel re- I name in the presence of two subscribing witlation with each other. 1 nesses.

2. In a device of the type set forth, the combination with the front and rear axles of a vehicle, of a spindle having a vertical member pivotally secured to each end of the rear FRANK'HENRY PIOKARD. Witnesses:
